Dual-ported RAM (DPRAM), also called dual-port RAM, is a type of random-access memory (RAM) that can be accessed via two different buses.. A simple dual-port RAM may allow only read access through one of the ports and write access through the other, in which case the same memory location cannot be accessed simultaneously through the ports since a write operation modifies the data and therefore ...
Dual-ported video RAM (VRAM) is a dual-ported RAM variant of dynamic RAM (DRAM), which was once commonly used to store the Framebuffer in Graphics card, . Dual-ported RAM allows the CPU to read and write data to memory as if it were a conventional DRAM chip, while adding a second port that reads out data.
DDR and DDR2 memory is usually installed in single- or dual-channel configuration. DDR3 memory is installed in single-, dual-, tri-, and quad-channel configurations. Bit rates of multi-channel configurations are the product of the module bit-rate (given below) and the number of channels.
However, it can open two memory pages at once, which simulates the dual-port nature of other video RAM technologies. The earliest known SGRAM memory are 8 Mbit [6] chips dating back to 1994: the Hitachi HM5283206, introduced in November 1994, [34] and the NEC μPD481850, introduced in December 1994. [35]
A single read or write operation for the DDR4 SDRAM consists of a single 8n-bit-wide 4-clock data transfer at the internal DRAM core and 8 corresponding n-bit-wide half-clock-cycle data transfers at the I/O pins. [20] RDRAM was a particularly expensive alternative to DDR SDRAM, and most manufacturers dropped its support from their chipsets ...
The laptop supports up to Intel Core i7 processor, up to 12 GB of RAM, up to a 2 TB HDD and up to a Nvidia 940M video card. The I/O consists of a combo audio jack, a VGA port, 2 × USB 3.0 port (s), 1 × USB 2.0 port (s), a RJ45 LAN Jack and a HDMI.

NetApp FAS3240-R5. Modern NetApp FAS, AFF or ASA system consist of customized computers with Intel processors using PCI.Each FAS, AFF or ASA system has non-volatile random access memory, called NVRAM, in the form of a proprietary PCI NVRAM adapter or NVDIMM-based memory, to log all writes for performance and to play the data log forward in the event of an unplanned shutdown.
